“We were delighted to have Emma Watson share the latest Our Shared Shelf book club choice, and she even wrote a lovely note to go inside the books,” said Cordelia Oxley, director at Books on the Underground.

“The reaction has been phenomenal. It must be a mixture of how much everyone adores Emma, and how exciting it is to find something as wonderful as a new book on your journey.”

The initiative was established in 2012, and distributes 150 books per week in public spaces.
